Vehicle to vehicle (V2V) communication could be widely available by 2017, according to U.S. regulators.

The Department of Transportation says that V2V technology could reduce the number of accidents on U.S. roads and decrease traffic. DOT officials expect the technology to be implemented by the end of Obama’s presidency in early 2017.

[1]The National Highway Traffic Safety Administration said that vehicle to vehicle communication could reduce the severity[2] of 80% of car crashes when the driver isn’t impaired. “Think of all the everyday situations that this technology could help with,” said U.S. Transportation Secretary Anthony Foxx.

The technology would be helpful “when folks pull up to a four-way stop, driving behind a big truck or an SUV that limits your visibility or even making a lane change and a car moves into your blind spot,” according to Foxx.

Additionally, drivers wouldn’t have access to the personal information of other drivers—they would only identify other vehicles if there’s a safety problem.
